Nyan Doom is a source port forked from DSDA-Doom by Andrik Powell (Arsinikk). It focuses on new experimental features and quality-of-life improvements over its parent port.

Features

• All features from DSDA-Doom:
  • MBF21, DSDHacked and DEHEXTRA support
  • UMAPINFO and COMPLVL support
  • Heretic and Hexen support
• Custom icons and executable (nyan-doom.exe)
• Expanded ENDOOM support, including the PrBoom+ ENDOOM window style
• Menu and automap translucent overlay similar to Woof! (with customisation)
• Native animated background and menu element lump support (for animated M_DOOM, TITLEPIC, INTERPIC, and even UMAPINFO background support)
• Native widescreen lump support for widescreen assets (avoiding the need for separate asset WADs)
• Native "berserk" and "armor" elements displayed near the status bar face
• GAMEVERS lump allowing a WAD to further specify a given game version if the COMPLVL value is set to "vanilla". It supports the values "1.2", "1.666", "1.9", "ultimate", and "final".
• True limit-removing demo support for vanilla complevels (0–4) to ignore overflow errors (via the -complevel #r parameter)
• When playing casually, game modifiers (pistol start, fast monsters, coop spawns, etc.) set by flags or config can later be changed in-game and are stored in savegames / rewind.
• Advanced Boom translucency options allowing customisation based on type (projectiles, powerups, and/or effects).
• Uses NYANHUD for extended HUD config (DSDAHUD as fallback).
• Additional extended HUD widgets:
  • status_widget, that shows currently active powerups as colored icons.
  • announce_message, similar to the "secret is revealed" message, prints the name of the map as a top-centred message.
• Additional experimental features:
  • "Smart" colored blood option for barons of Hell, Hell knights, and cacodemons (based on thing BITS and various other factors)
  • "Enhanced light amplification visor" effect (this keeps the dithered lighting effect, while raising the overall brightness. Areas under 64 brightness are then fixed to a static 64 brightness).
  • A "flashing item bonuses" option to make it easier to see health and armor bonuses.
• Additional quality-of-life features:
  • "Play demos while in menus" to play internal demos under the menu, a feature now removed in DSDA-Doom;
  • "skip IWAD demos in PWADs" to avoid playing desynced internal demos while on the title screen;
  • "skip IWAD story in PWADs" to skip the text screen in PWADs where the story text has not been changed;
  • "ignore IWAD map names" to avoid printing the IWAD map names on the automap or "announce map" message for PWADs;
  • "pause after intermission" to add a pause during the "Now Entering" screen for Doom II, Plutonia, and TNT (making it easier to read the map name);
  • and "full" and "subtle" options for the "announce map" and "secret revealed" messages.
• Re-introduced removed PrBoom+ features including "Linedefs w/o tags apply locally", "OpenGL blend animations", etc.

Launcher

The Nyan Doom launcher.

A Nyan Doom launcher forked from Pedro Beirão (PBeGood)'s DSDA-Launcher is available for download. It includes all the features of DSDA-Launcher, as well as some additional Limit-Removing features. The MacOS version of Nyan Doom includes this launcher built-in.

Current releases for the launcher may be found at its GitHub page.
